getListenerStats

The getListenerStats method provides a set of statistics about the listeners registered with the Metrics object, and is used for debugging purposes.

getListenerStats(): MetricsListenerStats

The method is intended to be used during development to ensure your application is not leaking listener registrations, for example.

import {createMetrics, createStore} from 'tinybase';

const store = createStore();
const metrics = createMetrics(store);
metrics.addMetricListener(null, () => console.log('Metric changed'));

console.log(metrics.getListenerStats());
// -> {metric: 1}
